Re: Acoustic Revive DSIX 12 volt Power supply

The magic of the synchro-isolator design is in the design concept and schematic. With a decently laid-out circuit board, building the circuit shouldn't be particularly challenging. If the guys doing the circuit-board layout and assembly are competent and can follow directions precisely, I fail to see why there is any need to enlist the assistance of old veteran audio craftsmen (^o^).

FWIW, the flying cap / synchro-isolator principle has the potential to be very much more battery-like and quiet than any conventional AC mains-driven power supply. If the DPS1 was conventional in its approach, the King-Rex is likely a good substitute, and the synchro-isolator circuit will likely sound better than either (Shibazaki noted that the choice of power supply used had a clear effect on the sound of the DSIX). If the DPS1 is based on the synchro-isolator circuit or is similar in approach, it would be the one to get.

I don't remember if I own the commercial version of the DSIX or not, but I do have Shibazaki's hand-drawn schematic for Generation 11. This uses an EIAJ-4J power connector with the center as +12V and the surrounding ring as ground. If in doubt, I would ask the advice of a competent electronics technician, since he should be able to tell you what the polarity should be (and rewire the umbellical cable if required).

BTW, if you want to see more information, the M&J issue that contains the DSIX article introducing the synchro-isolator is December 2000. regards and hth, jonathan carr

You make it sound so simple, where can one find this December 2000 M&J issue that contains the DSIX article introducing the synchro-isolator?
Is it still on sale, or on an online archive that we can refer to?
You can actually see a big picture of the internals of the DPS1 power supply on Dagogo review of the DSIX. Can you tell from that what circuitry it's based on? I assume that you will be qualified enough to tell based on the circuitry how a production assembly should look like. ;-)
If the DPS1 is not based on that flying capacitor model, please advise where can we get a commercial product based on it. I don't DIY. If I can find a DIYer or good freelancer modder to do it, how much do you think is a reaasonable price to pay for this customised model?
Thanks in advance for any info.

  Of course the December 2000 issue of M&J is no longer on sale. But at least I have given the information on what issue to look for, I've posted a schematic, and this should be of considerable help for those motivated enough to hunt down a copy. I have all of the M&J issues from that time, I also have some notes and schematics regarding the DSIXs from Shibazaki, and I thought that sharing some of this information would perhaps be appreciated.
  
  At any rate, I looked up the photo of the DSIX on Dagogo, and I feel fairly certain that it is a synchro-isolator circuit (and so it should be superior to the KingRex). But as the photo shows, this is a damn simple design. The amount and complexity of wiring is minimal, and the parts count and layout isn't even complex enough to warrant a double-sided circuit-board. The parts themselves don't appear esoteric enough to be much of a bottleneck, either. I believe that the green Muse electrolytics are out of production, but Nichicon does offer suitable replacements today.
  
  I'd suggest that someone who has a year or two of producing electronics commercially and is reasonably motivated and competent should be able to handle this. No need for decades of experience here.
  
  As for how much it would cost for someone to replicate the DPS1, the cost of living and salaries differ considerably around the world, so I cannot offer any useful information. jonathan carr
  
  PS. Do yourself a favor and get rid of the self-entitled attitude that you are projecting. The only thing that you will accomplish is to de-motivate those who would otherwise be willing to post and offer advice.
